Bd. 1. Metrisierung, Hypothesenbildung, Theoriendynamik.--Bd. 2. Experiment, Erklärung, Prognose.

In der 1970 gegr ndeten Reihe erscheinen Arbeiten, die philosophiehistorische Studien mit einem systematischen Ansatz oder systematische Studien mit philosophiehistorischen Rekonstruktionen verbinden. Neben deutschsprachigen werden auch englischsprachige Monographien ver ffentlicht. Gr ndungsherausgeber sind: Erhard Scheibe (Herausgeber bis 1991), G nther Patzig (bis 1999) und Wolfgang Wieland (bis 2003). Von 1990 bis 2007 wurde die Reihe von J rgen Mittelstra mitherausgegeben.

The article shows that the currently fashionable idea of an omnipresence of mediality is already effective in some areas of medieval thought, even though in another form. The medieval conception of the relation between god, the world, and man implies a theological world view, according to which the phenomenon of mediality is not only universally present in the world, but in which the mundus creatus itself appears as a medium par excellence, as a message to man, assisting him in transcending (...) that medium. Furthermore it is argued that medieval philosophical thought is by no means restricted to such a symbolic world view. Scholastic philosophy does not only come with a highly elaborate theory about the different forms of cognitive media, but also has developed, particularly in the context of logic, a thoroughly rational theory of the sign and its functions, by which the symbolic and allegorical thinking was pushed to the margins of the philosophical discourse.

"Domestizierung lässt sich durch einen Nukleus aus drei technischen Tätigkeiten definieren: durch die gesteuerte Reproduktion, die eigens eingerichtete Ernährung und den Schutz von Tieren und Pflanzen vor Schädigungen. Wenn man diese Definition an einen Vergleich von Kulturen und Kollektiven anlegt, stellen sich zwei Überraschungen ein: Außerhalb jeder Domestizierung entwickeln Wildbeuter eine rituelle Domestizierung oder ein mythologisches Verständnis, ihre Welt sei bereits domestiziert. Und in der Moderne tritt an die Seite der technischen Domestizierung ihre mögliche Naturalisierung. Der Aufsatz zieht einige Konsequenzen (...) aus diesem typologischen Vergleich. Domestication can be defined by a nucleus of three technical activities: controlled reproduction and nutrition as well as protection of animals and plants from damage. If one applies this definition to a comparison of cultures and collectives, two surprises arise: Without being in touch of any kind of domestication, hunter-gatherers develop a ritual domestication or a mythological understanding that their world already is domesticated. And in modernity, possible naturalization arises at the side of technical domestication. The paper draws some conclusions from this typological comparison. ". (shrink)

Ever since Parmenides, one of philosophy's riddles has been how we are able to direct our thoughts to non-being. Erhard uses the problem of non-existence as the starting point for an analysis of Husserl's phenomenology. He examines Husserl's interpretation of judgments about non-being as judgments made "under assumption" and his analysis of "free fantasy." Erhard thus demonstrates that Husserl is compatible with today's non-relational theories.

The paper focuses on some aspects of the early modern aftermath of supposition theory within the framework of the protestant logical tradition. Due to the growing influence of Humanism, supposition theory from the third decade of the sixteenth century was the object of general neglect and contempt. While in the late sixteenth-century a number of standard textbooks of post-Tridentine scholastic logic reintegrated this doctrine, although in a bowdlerized version, it remained for a century out of the scope of Protestant logic. (...) The situation changed when the Strasburg Lutheran theologian J.C. Dannhauer, who in 1630 developed and propagated the program of a new discipline which he called ‘general hermeneutics’, accentuating the importance of supposition theory as an indispensable device for the purpose of textual interpretation. Due to Dannhauer’s influence on later developments of hermeneutics, which in the seventeenth and early eighteenth centuries was regarded as a logical discipline, supposition theory is still present in several logical treatises of the eighteenth century. The explication of the underlying views on the notion of supposition and its logico-semantic function may give at least some clues as to how to answer the question of what supposition theory was all about.

In this paper I argue that the almost forgotten early dissertation of the phenomenologist Hans Reiner Freiheit, Wollen und Aktivität. Phänomenologische Untersuchungen in Richtung auf das Problem der Willensfreiheit engages with what I call the unity problem of activity. This problem concerns the question whether there is a structure in virtue of which all instances of human activity—and not only “full-blown” intentional actions—can be unified. After a brief systematic elucidation of this problem, which is closely related to the contemporary “problem (...) of action,” I elaborate and critically discuss two relevant threads running through Reiner’s work. The first view concerns the alleged motivational asymmetry between activity and passivity according to which it is essential only for active experiences to be motivated by an underlying passivity. The second view focuses on Reiner’s phenomenology of the will, especially on his notions of “ego-centrality” and “inner will” the latter being introduced in analogy to Brentano’s notion of “inner consciousness.” These two notions are supposed to unify all manifestations of the human will, including “full-blown” intentional actions and non-intentional doings such as laughter. Reiner’s extension of will-based actions to non-intentional activity is one of the most remarkable aspects of his early work. Finally, I show that Reiner ultimately answers the unity problem in the negative because he ends up with the view that besides will-based agency he also acknowledges so-called “motor activity” which is not intrinsically related to the will. I close with a couple of tentative proposals how volitional and motor actions might be unified nonetheless. (shrink)

Hermann Weyl was one of the early contributors to the mathematics of general relativity. This article argues that in 1929, for the formulation of a general relativistic framework of the Dirac equation, he both abolished and preserved in modified form the conceptual perspective that he had developed earlier in his “analysis of the problem of space.” The ideas of infinitesimal congruence from the early 1920s were aufgehoben in the general relativistic framework for the Dirac equation. He preserved the central idea (...) of gauge as a “purely infinitesimal” aspect of symmetries in a group extension schema. With respect to methodology, however, Weyl gave up his earlier preferences for relatively a-priori arguments and tried to incorporate as much empiricism as he could. This signified a clearly expressed empirical turn for him. Moreover, in this step he emphasized that the mathematical objects used for the representation of matter structures stood at the center of the construction, rather than interaction fields which, in the early 1920s, he had considered as more or less derivable from geometrico-philosophical considerations.

Inwiefern ist Metaphysik heutzutage noch relevant? Gibt es einen Sinn, in dem Metaphysik fur die Philosophie unverzichtbar ist? Was ist gute Metaphysik, und worin unterscheidet sie sich von schlechter Metaphysik? Was sind Chancen und Probleme genuin metaphysischen Denkens? Die Beitrage des Sammelbandes widmen sich diesen Fragen aus historischer und systematischer Perspektive.
